Patented. Aug. 10, 1909.

Application filed. May 24,1909. Serial No. 497,899.

To all whom it may concern:

State of Alabama, have invented a new and Improved Cultivator, of which the following is a full,.clear, and exact description.

Thls invention relates to cultlvators such as used in tilling growlng crops.

The object'of the invention is to produce a cultivator of simple construction, the teeth of which may be adjusted so as to change their distance apart as maybe desired, and further to provide a construction which will enable the teeth to be adjusted as to their elevation to adapt the implement for use on ahillside or ridge. a

The invention consists in the construction and combination of parts, to be more fully described hereinafter and particularly set forth in the claims.

cation, in which similar characters of ref erence indicate corresponding parts in all the figures. v V v Figure, 1 is a plan of 'a cultivator constructed according to my invention, a portion of the tongue or pole being broken away; Fig. 2 is a side elevation of the implement, the pole being broken away; Fig. 8 is a vertical section taken in a transverse plane and showing substantially one-half of the implement, in this view theparts are represented in dottedlines so as to illustrate one of the possible adjustments of the imple-j ment; Fig. 4 is a cross section through the hoe bars taken in a front and rear plane and especially illustrating the manner of mounting the hoes or teeth, in this .view the body of the tooth or hoe is shown inelevation; Fig. 5 is a vertical sectionthrough the rear portion ofthe implement and illustrating a guard which runs over the row, in this connection it should be understood that the cultivator is. intended to cultivate on each side of the rowof plants; Fig. 6 is a plan showing a modified form of a segment which constitutes a feature of-the invention; and Fig. 7 is a section showing a bracket which aifordsmeans for attaching the guard.

Referringmore particularly to the'parts, 1 represents the tongue or pole of the imple ment. Near the rear end of this pole, and on the under side thereof a Z-bracket2 is attached, the upper arm 3 whereof is provided with a longitudinal slot 4, as indicated in Be it known that I, ARTHUR BRIGDEN, a citizen of the United States, and a resident of Albertville, in the county of Marshall and Fig. Through the medium of this slot, the bracket is attachedby means of a bolt 5,

which passes through the beain, as indicated. The lower arm 6 of this Z-bracket extends .rearwardly, and at its rear end, a hinge connection 7 is made with a trailer bar 8. To this trailer bar 8 a guard" 9 is attached, said guard being formed of two substantially rectangulary0kes10, to the lower ends of which side platesor guard'plates 11 are attached, as shown, andthe forward edges of these guard plates are tapered, as indicated in Fig. 2. It shouldbe understood that as the implement advances, this guard straddles the plants and protects them from being accidentally up-rooted by the teeth of the cultivator. The guard also operates as a guide for the implement. The implement is, of course, drawn along by two horses, a horse j I being on each side of the tongue. Reference is to be had to the accompany. ing drawings formlng a part of thls specifi- To the under side of the tongue, and forwa rd of the guard 9, semicircularsegments 12 areattached. Each of these segments is connected by a hinge connection 13 with an anchor plate 141, and these anchor plates are attached by pivot bolts 15 which pass upwardly through the pole, as indicated in Fig. "3. Each segment 12 is provided with an arcuate slot 16, said slots being disposed about the center of the segment as an axis. These slots 16 are provided in their outer edges with a plurality of notches 17 spaced equidistant, as shown. The segments 12 are disposed about a center bolt or king bolt 18,

as, anaxis, and by means of this bolt 18, on the under side of the tongue, anchor plates 19 are provided which have hinge connections for attaching transverse rear hoe bars 20.' Forward hoe bars 21 are provided which are similar to the hoe bars 20, and which are also attached by anchor plates 22 having hinge connections 23. The anchor plates 22 are attached by a pivot bolt 24 similar to the bolt 18. In the bars 20, near the position of. the slots 16, short slots 25 are formed, as indicated in Fig. 3, and through these slots clamping bolts-26 pass. When the nuts of these bolts 26 are loosened, these bolts 'may be slid inwardly toward the tongue so as to disengage them from the notches 17,. and: at this time the bars 20'may be swung in a frontand rear direction on the axis of the bolt 18 as a pivot. The bars 20 and 21 are connected by short braces or straps 27, and at the middle points anchor formed of two sections 33 and 34 which have.

their flat faces set together, as indicated. These sections are provided with longitudinal slots 35 having equidistant notches 36 formed in the side edges thereof. These notches may aline with each other, and through the slots or through the notches, a clamping bolt 37 passes. This bolt securely clamps the two sections together, and prevents them from sliding longitudinally with respect to each other. The upper section 34, as indicated in Fig.3, is provided at its upper end with a downwardly projecting tip 38, and this tip projects into the slot of the lower section. This maintains the parts in alinement, as will be readily understood, and enables me to use a single bolt at this point, instead of two bolts. The anchor plates 28 and 29 are attached to the tongue by a pivot bolt 29.

In Fig. 3, the cultivator is shown in its normal position as to the elevated adjustment of the hoes. In dotted lines in this View I indicate the manner in which the elevation of the hoes may be altered. In order to adjust the hoes as suggested, it is only necessary to release the bolt 37 and extend the extensible links 31, as indicated by thedotted lines. This permits the adjacent segment to swing down into an inclined plane, as shown. The manner of securing the hoes 39 to the hoe bars will now be described: The bodies of these hoes 39 are disposed horizontally, as shown in Fig. 4, and the rear ends are formed into teeth 40 which till the soil, as will be readily understood.

V faces of these brackets. Through the brackets and through the extensions 44 a clamping bolt 45 passes, and at the junction of the head with the body of the hoe, an angle brace 46 is formed on the forward and under side, and this angle brace is also attached by means of the bolt 45. The bolt is inserted so that its head is on the forward side of the forward angle bracket 42, and three clamping nuts 47 are provided, two of which clamp the angle brace 46 and the bracket 42 against opposite sides of the rear vertical extension 44 of the head 41. When the links 31 are extended, as indicated by the dotted lines in Fig. 3, the holes 39 are adjusted so as to ing the holes on the axis of the bolt 45 until they come into the position shown in Fig. 3,t.hen the nuts are clamped again.

In Fig. 3 I simply show how the vertical adjustment is accomplished on one side of the cultivator, but it should be understood that a similar adjustment can be effected on the opposite side so that all of the teeth of the cultivator will be disposed along an inclined line, as indicated by the dotted lines. Similarly, in Fig. 1 I have shown by the dotted lines the manner in which the right side of the cultivator may be adjusted, but it should be understood that the other side would be similarly adjusted in actual practice. ment the width of the cultivator can be changed at will. so as to suit the circumstances or the particular requirements.

Special. attention is called to the notches 17 and 36. it should he understood that I do not depend upon the frictional force of the clamping bolts to hold the parts in position, and this is a highly advantageous feature. On account of the slot 4, the bracket 2 may be adjusted in a front and rear direction, as desired. To the rear end of the tongue a handle 48 is attached, which handle may be of the common form illustrated. If desired, instead of using the notches 17, where the work is of a very light character the clamp ing force of the bolts may be sufficient to hold the parts in position, in which case I may adopt the form of segment shown in Fig. 6. Referring to this view, 49 represents the segment which is simply a plain curved bar having a plain slot. 50 with no notches whatever. This segment is attached in the same manner as the segments 12 and operates in substantially the same way, except that I rely solely upon the clamping force of the bolts to hold the parts rigid.

Having thus described my invention, I claim as new and desire to secure by Let ters Patent,
